HONOLULU (AP) - A representative for Alex O'Loughlin says the “Hawaii Five-0” star is taking time away from the show to get treated for problems related to pain medication.

Rachael Wesolowski says in a report by the Honolulu Star-Advertiser ( http://bit.ly/xJ11ez) that O'Loughlin ” is taking a short break to receive supervised treatment for prescription pain medication due to a recent shoulder injury.”

Series producer CBS Television Studios and O'Loughlin representatives declined to comment on the nature of O'Loughlin’s injuries or his treatment.

O’Loughlin, who portrays crime fighter Steve McGarrett, is known for doing many of his own stunts on the action-packed show. The paper says he reportedly will be absent for at least one episode.

CBS says in a statement that “everyone at CBS Television Studios and `Hawaii Five-0’ wishes him well and we look forward to his return.”
